WILLIAM H. GRAY, OF BROOKLYN, NEW YORK, ASSIGNOR TO THE GLEN COVEMACHINE COMPANY, (LIMITED,) OF SAME PLACE.

PRESSER-BAR FOR WOOD PLANING OR MOLDING MACHINES.

SPECIFICATION forming part of Letters Patent No. 361,506, dated Aprill9,1887.

Application filed February 11, 1887. Serial No. 227,262. (No model.)

' has been commonly hinged at one side of the machine, and at theopposite side thereof has been inserted in a loop or shackle orotherwise held in place, so as to provide for its adjustrnent upward anddownward.

In carrying out my invention I hinge the abovedescribed cross-bar at oneend, as has been before done; but I provide anovel means of securing thebar at its free end, which enables the bar to be adjusted accuratelyupward and downward, and which also provides for expeditiously freeingthe end of the bar from the means which hold it, in order to swingthebar upward away from the cutter-head; and the invention which relates tosuch means for holding and adjusting the free end of the bar consists innovel combinations of parts and features of construction, hereinafterdescribed, and pointed out in the claims.

In the accompanying drawings, Figure 1 is an elevation in a planetransverse to the length of the machine, showing the parts which arenecessary to illustrate my invention, thecutter-head and the side framesand bearings being shown in dotted outline. Fig. 2 is a plan of theparts shown in Fig. l by full lines. Fig. 3 is an end view of the partsshown in Fig. 1, looking from the right hand of said figure; and Fig. 4is a horizontal section upon about the plane indicated by the dottedline :0 m, Fig. 3.

Similar letters of reference designate corresponding parts in all thefigures. 4

A designates the lower cutter-head, A the cutter-head boxes, and Aportions of the side frames of the machine, all of which parts are shownin Fig. l by dotted lines, as they donot directly concern my invention-B is a cross-bar, which is usually arranged above the lower cutter-headand transversely of the machinein awood-planing machine, and upon thisbar is a presser, which, as here shown, consists of a stock-piece, C,secured to the bar B, and an adjustable foot piece or presser, C, whichmay, by means of a screw, 0, be adjusted upward and downward relativelyto the stock-piece C and the supportingbar B. The bar B is usuallyhinged at one side of the machine, and its free end is connected withmeans at the opposite side of the machine whereby the bar may beadjusted upward and downward and held securely in po sition after suchadjustment. the bar I have represented a bracket, D,whioh may be boltedto one of the side frames of the machine, and to which the upright linkor post E is hinged or pivoted at e,and at the other or free end of thebar is a bracket, D, from which rises a round post or column, E. The endof the bar B may be pivoted or hinged at e to the upright link orconnection E, and the slot 6 in the link or connection E provides foradjusting that end ofthe bar upward and downward to suit considerablevariations in height.

The means for securing the free end ofthe bar in place, and foradjustingit upward and downward, consist of a head, F, upon the post or column E,a collar or slide, F, which is fitted to both slide and turn upon thepost E, and a screw, F which has its bearing f in the head F and whichis threaded to engage a nut formed ILtlle collar F. The collar F has onone side a flattened surface, f, on which the free end of the bar B issecured by means of aclampingscrew, f and the free end of the bar mayhave in it a slot, b, as shown by dotted lines in Fig. 1, through whichthe clampingscrew f passes. WVhen the clamping-screwf is tightened, theend of the bar B is held securely against the flattened surface f of thecollar F; but it will be observed that the slot 2) provides for turningthe collar upon the post E whenever the clamping screw f is loosened, inorder to remove the clamping-screw entirely from the bar B andpermitsaid bar to be swung upward. The adjustment of the bar upward anddownward is provided for by turning the screw F". After the free end ofthe bar At one end of cured by turning the screw F, and the bar betweenits periods of adjustment is held with sufficient firmness and rigidityto'euable the presser O to properly perform its work.

The head F and the collar F are both fitted to turn freely on the postE, and whenever the bar B is freed from the clamping-screw f or wheneversaid screw is slightly released, the head F, the collar F, and the screwF may be turned on the post E as one piece,to disengage and leave freethe end of the bar B.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with the lower cutterhead and side frames of aplaning or molding machine, of a bar carrying a presser extending acrossthe machine and hingedlat one end on one side of the machine, a post atthe other side of the machine, a slide movable vertically on the postand to which the end of the bar may be secured, and ascrew,substantially parallel with the post, by which the slide may beraised and lowered, substantially as herein de scribed.

2. The combination, with the bar B, hinged atone end and carrying apresser and slotted at the other end, of the post E, the head F, and thecollar F, both fitted to turn on the post and the collar being providedwith a fiat face, f, and a clamping-screw, f, forsecnring the bar, andthe adj usting-screw F connecting the said head and collar and servingto adjust the collar vertically on the post, substantially 35 as hereindescribed.
